Crazed Patterson, who kidnapped Closs, 13, and who held her for almost 90 days after killing both her parents religiously followed websites including RadarOnline.com to monitor what was happening.
Patterson, 21, of Gordon, Wisconsin "learned the names of the two people he shot and killed after seeing their names reported on multiple news programs and social media," the criminal complaint reads.
"The assailant followed several social-media groups that are also monitored by local, state and federal authorities," a source close to the investigation told RadarOnline.com.
"He followed one group in particular very closely. The group is operated by BADmins, and they are known for having a large following of crime buffs from around the world who share theories."
The BADmins group consists of over 100,000 members from 6 countries, and the source noted that authorities monitor the group for any potential leads in many cases, including Colorado killer Chris Watts and the murder of Iowa native Mollie Tibbetts.
"During the Chris Watts case, it was made public that Chris' alleged mistress also followed the group, sending screen shots of posts to local, state and federal authorities on the case."
"He was very intrigued by the BADmins group from his online history," the source close to the investigation revealed. "He was on it at least twice per day - logging in once in the morning and once at night."
The source noted that the suspect also monitored RadarOnline.com, DailyMail, CNN, Reddit and even tuned into 'All Rise' with Dylan Howard on Nov. 16 when Barron County Sheriff Chris Fitzgerald appeared on the show.
The self-confessed criminal also followed local television coverage and scoured the internet to learn new facts.

Jayme Closs had been missing since October 15, 2018 when her parents Denise Closs and James Closs were found murdered in their Wisconsin home and the 13-year-old was nowhere to be found.
In a shocking twist, the source believes that he was watching television coverage on the case while Jayme could overhear what was being said on television.
"It appeared that the suspect watched the news on a regular basis and followed all television specials on the case. It is believed that Jayme could hear the press conferences from where she was held captive - she knew that local, state and federal authorities were not giving up. In a way, it was a way to give her some peace of mind - she knew that the world was looking for her," the source said.
RadarOnline.com revealed exclusive images from inside the creepy Wisconsin cabin, which belongs to alleged kidnapper Jake Thomas Patterson's family.
The source previously told RadarOnline.com that Jayme's kidnapping was eerily similar to that of Amanda Berry, who was tortured and held captive for 10 years in Cleveland.
Patterson is currently behind bars in lieu of $5 million cash bond after, according to the criminal complaint obtained by RadarOnline.com, confessing to murdering Closs' parents in cold blood before abducting the teenager and holding her captive for nearly three months.
